ROLL FOR BEATING-ENGINES.

Specification of Letters Patent.

Application filed August 2, 1917. Serial No. 184,126. I

1 '0 all whom it may concern:

Be it known that CLARENCE P. FoLsoM, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, has invented certain new and useful Improvements in Rolls for. Beating- Engines, of which the following is a specification.

This invention relates to improvements in rolls for beating engines and more particularly to the means for fastening the flybars in position so that they are held securely in the roll and may be conveniently and expeditiously removed and replaced when necessity requires. It will be understood that. such rolls are employed for beating stock or pulp in the paper-making art, and that owing to such usage the fly-bars are called upon to withstand a very considerable amount of stress or strain and have,'thercfore, to be securely held in position against any vibration or looseness in the operation of the engine. Owing to the requirement of. rigidity in their mounting and the facility with which they maybe re moved and replaced when occasion requires it is the object of the present'invention to provide securing means of a substantial character in the form of specially constructed supporting rings or frames more particularly the means for securing the fly-bars therein, as will hereinafter more clearly ap pear from the description to follow and the accompanying drawings. 7

Referring in general terms to the accompanying drawings, Figure 1 represents a vertical sectional view of a beating-engine roll embodying my improvements. Fig. 2 is a somewhat enlarged fragmentary view of the periphery or ring of one of the supporting frames partly in section, showing the fly-bars in position therein. .Fig. 3 is a view on the line 33 of Fig. 2 showing the periphery or ring of one of the supporting frames partly in section and the fly-bars in cross section. Fig. 4f is a sectional view on the line H of Fig. 2 and Fig. 5 is a detail elevation of a portion of the periphery or ring of a supporting frame, showing the inner side thereof.

In the more particular description to follow, like reference characters indicate similar parts throughout the description and drawings.

The heater roll comprises a series of spiders or supporting frames 1 which are assembled in proper relative position on shaft 2 and made-fast thereon. The periphery or marginal ring of each spider or frame 1 consists of a ring 3, the base of which eX- tends laterally as at spider or frame is provided with slots or openings 5 at uniform distances throughout the ring for the reception of the fiy-bars (3 which snugly fit therein. .The. fiy-bar openings 5 on theytwo end spiders or frames do not extend through the periphery or ring portion 3 because the ends of the fiy-bars 6 terminate at these two end spiders.- There is therefore a shoulder 7 formed at the inner end of each of the openings 5 of end spiders or frames against which the ends 7 of thefly-bars abut. The width of each opening 5 is sufiicient to snugly receive the inserted portions of the fly-bars. The flybars, it will be seen, taper on one side longitudinally while the other side is straight and the walls of the openings 5 are similarly shaped to receive them. This construction of the fiy-bars gives them a wedgelike fit in theopenings 5 which is largely depended upon to hold them firmly in position. The openings 5 being of a width to snugly receive the inserted portions of said fly-bars there is thus provided solid walls of hard metal between which the fly-bars, are held. This provision prevents the fly-bars from having any lo'oseness or vibration. Atan intermediate point in the depth of the openings 5 there are provided on each side recesses 18 which extend farther into the walls of the openings 5. These recesses 78 open out on one side of the ring 3 and termie nate in inner abutments or shoulders 9, as seen in' Fig. at. The said recesses 8 receive pins 10 which pass through-horizontal and oblong openings 11 in the fly-bars-the portions of the fly-bars lying within the openings 5. As shown in the drawings the pins 10 pass through the openings in the fly-bars and lie across the openings 5, with their ends in the recesses 8. It will be observed that the openings 11 in the fly-bars are of a length to extend inwardly beyond the inner side of'the ring 3; therefore the pins 10 may be inserted in the recesses 8 by pass ing them in through the exposed end of openings 11 as seen'in Fig. 4 and thence into said recesses. This provision enables the openings 11 to be extended between the walls in the ring 3below the outer circumferential surface of thering 3 so, that there may be The ring 3 of each.

an upper shoulder 8' which looks the pins 10 from any outward movement. The object and purpose of the pins 10 is to contribute to holding the fiy-bars in position against any outward movement 'due to centrifugal force. Wh n the pins 10 are placed in position they are secured by a surrounding body of metal 12 of a character which has a low-melting point such for example as lead or Babbitt metal. This metal in melted form is poured into the recesses 8 to fill the space around the pins 10 to the outer terminal of said recesses and to fill the openings 11 in the fly-bars. The molten metal is poured into the re cesses 8 through openings 13 in a block 14-. The block as shown in Fig. 2 is held against the inner side of the ring 3 between two fly-bars. The opening 13 in said block 1 1 communicates with the inner or exposed end of the opening 11 in the fly-bar and through this opening 13 the metal is poured through said opening 11 and into the recess 8 around the pin. A similar block 15 is placed in a position on the other side of the adjacent fly-bar. This block 15 has no opening 13, its purpose being to block up the other side of the fiy-bar opening 11 while the metal is being poured through the opening 13. The blocks 14 and 15, it will be understood, are utilized only to pour the melted metal. After this operation is done they are removed. The metal 12 may be remelted and removed from said recesses 8 by applying a torch thereto and turning the supporting frame 1 to bring each opening 16 in a vertical position for the melted metal to drain out of the recesses 8. The openings l6-are relatively small openings that extend into the ring 3 on one side of the fiy-bar at a right angle to the recesses 8, and they communicate with the recesses 8, and when the metal is removed and the pin 10 is free to be displaced, a small tool or implement may be inserted through the opening 16 and the pin pushed out. The openings 17 in the ring 3 at the base of the openings 5 are for convenience in machining the openings 5. They enable the planer or other tool used in machining the openings 5 to be easily removed. Between the fly-bars and running parallel therewith it is customary to provide wooden bars or fillers which expand and become rigid in their positions and contribute in securely maintaining the fiy-bars in position. In Fig. 3, 18 designates one of such wood fillers which is thought to be sufficient illustration of these parts owing to their well-known utility.

From Fig. 3 it will be readily seen that the fiy-bars are in direct contact with hard metal, to wit, the side walls of the openings 5 and at no point is the softer'metalrequired to Withstand the strain exerted on said fly-bars. The softer metal is required only for locking the pins 10 in their position. The openings in the fly-bars are made oblong so that the softer metal may be poured in the recess 8 and thus avoid increasing the openings 5.

Having described my invention, I claim:
